CONEXPO Introduction for Terex Finlay’s new J-1170 primary mobile jaw crusher
The new Terex Finlay J-1170 primary mobile jaw crusher
Nigel Irvine, Terex Finlay sales and marketing director says the company’s new J-1170 high performance primary mobile jaw crusher’s 45tonne transport weight and compact dimensions mean lower transport costs between and within crushing sites.
Built around the Terex 1,100mm x 700mm jaw crusher and with a proven track record in recycling, aggregate production and mining applications, the machine is said to offer excellent material reduction and product sizing in the processing of blasted quarry rock and ore material. The jaw chamber is also available with optional hydraulic release, an excellent feature when crushing construction and demolition debris.
The hydraulic release option has an automatic overload protection system to prevent damage by uncrushable items in the feed material.
The machine is powered by either a Tier 3/Stage 3A Caterpillar C9 261kW or a Tier 4i Scania DC9 70A 257kW.
Hydrostatic transmission of the jaw chamber offers operators reversible operation in the event of a blockage, and the hydrostatic system also provides variable chamber speed to suit given applications. The crusher features hydraulic assist chamber CSS (closed side setting) adjustment, and can be changed in minutes.
The machine has a heavy-duty variable speed vibrating grizzly feeder (VGF) with integrated pre-screen, providing an aggressive action to separate fines material efficiently, says Terex Finlay. The variable speed VGF ensures continuous choke feeding of the crushing chamber for optimal productivity. Material from the pre-screen can be diverted to a stock pile via the onboard bypass conveyor or join the crushed product on the main belt.
The large 9.6m³ hopper has hydraulically folding sides and an innovative hydraulic self-locking mechanism to provide efficient and faster machine set-up and tear-down times.
“The robust and intelligent chassis design, with good clearance on both ends, also enables safe and easy loading onto all transport trailers. When you combine these factors with the excellent crushing capabilities the machine easily meets the demands of owner operators and crushing contractors,” says Nigel Irvine.
